Our Story

GroDev is a solo full-stack development studio founded by Dominik Groński in Poznań, Poland (May 2026). Before GroDev, 6+ years leading retail operations under SLA pressure — that background shapes how I build systems: for production, not portfolio.

Focus: custom CRM/portals, 3D configurators in Three.js, AI integrations. Direct communication with the developer writing your code. Client code ownership from day one. Zero SaaS lock-in.

What Sets Us Apart

Solo Senior Delivery

You talk directly to the developer writing your code. No account managers, no juniors doing the actual work.

Client Code Ownership

Your repository on your GitHub from day one. Zero SaaS lock-in.

Honest Fixed Pricing

Written brackets before we start. No hidden "starting from" or scope creep surcharges.

Commonly Asked Questions

Weekly status update via email with milestones progress, blockers, and next steps. Async communication via Slack or Discord for daily questions (response within 4-8h business days). Video calls scheduled Mon/Wed/Fri when needed. All decisions documented in a shared project doc for asynchronous review. All code changes visible in real-time via your GitHub repository — you always have full visibility.

Custom CRM systems, client portals, 3D product configurators (Three.js), AI integrations (Claude/OpenAI), custom e-commerce (Laravel/Vue), and nearshore engagements for DACH/UK clients (€40-75/h). Sweet spot: PLN 15,000-90,000 (~€3,500-€21,000), 6-14 week timelines. Also open to smaller landing pages (from PLN 1,500) and enterprise projects (PLN 150,000+) with 3-6 month timelines.

1. Kickoff call (30 min discovery). 2. Written scope with fixed brackets delivered within 24-48h. 3. Weekly milestones with staging environment preview. 4. GitHub as single source of truth — client has admin access from day one. 5. Payment schedule: 40% deposit, 40% at MVP staging, 20% at go-live. 6. 30-day guarantee post go-live for bug fixes. 7. Ongoing SLA available (MONITOR, CARE, PRIORITY packages).
